This summer, beat the heat with your own air conditioner.
Cost Ecient System
Your new air conditioner not only provides maximum cooling power in the summer, but can also be an ecient heating
method in the winter with the advanced“Heat pump”system. This technology is up to 300% more ecient than electrical
heating, so you can further reduce its running cost. Now, meet year-round needs with one air conditioner.
Flexible installation

air ow requirements. Also, the air intake can be set up on either the bottom or rear of the unit, so there is more exibility in
installation.
